I purchased items of the same part number before, but printing became considerably thinner compared with the previous one. It seems to suppress the ink cost, but whatever it is, it becomes too thin extremely. Saying it is a handwritten invoice, it is regrettable because this is undisputed. I would like to use something different if this quality will continue in the future.

Since it has been used for many years, it will not be changed, but it draws the underlay so that it does not appear below, but in the past it was thick and good, but now the underlay is thin. One piece, sandwiching alone, letters on the paper below. I can finish writing two sheets at last. Is it a matter of power?
